SPECIFICATION forming part of Letters Patent No. 274,753, dated March l27, 1883.

Application led December 1, 1882. (No model.)

To all whom it may concern Be it known that I, WILLARD M. FULLER, of New York, in the county and State of New York, and a citizen of the United States, temporarily residing at Lexington, in the county of Davidson and State of North Carolina, have invented new and useful Improvements in Gar-Heaters, of which the following is a specication.

The object of this invention is to provide a furnace for heating railroad-cars from underneath and outside of the car, and which shall be compact and readily applied to a car with but a slight change in the latter, which shall be convenient, simple, and efcient in every particular, and by which, with but a slight expenditure of fuel,the car can be comfortably and constantly heated. These objects I attain by means of the devices illustrated in the annexed drawings, in which- Figure l represents a vertical central section of my improved heater attached to a car. Fig. 2 is a like view taken on a plane at right angles to Figfl. Fig. 3 is a plan view of the boiler with the steam-dome in section and a portion of the boiler broken away. Fig. 4 rep resents the ash-pit and the grate resting in itsseat. Fig. 5 is a bottom view of the ashpit.

A indicates the boiler, which consists of a short cylindrical body cast with a flange, c, aroundfits upper edge, a pair of lugs, a', extending laterally from such flanged edge, and a tubular neck, a2, which rises from the top and constitutes the steam-dome of `the boiler, as a safeguard from lire. To provide an in creased area of heating-surface, I secure in the bottom ofthe boiler a set of short tubes, B, which depend from the boiler, and are closed at their lower ends. These tubes may bemade of any shape, size, or style. In securing this boiler in position its dome or steam-jacket is passed'upthrough an opening in the :door ot the car, and its top is held against the iioortimbers C by means of bridges or cross-bars" C', which are fitted against the under side of the lugs c and secured to the timbers. This forms a simple and effective mode of securing the boiler and admits of its being readily removed when necessary.

D indicates a metal plate which is secured to the door at apoint above the steam-jacket. Thisl plate has an opening which registers with the upper end of' the steam-dome, :as illustrated in Fig. 1. A metal cap, E, which has its flanged top Iitted inV said opening, has its body portion c fitted vin a vertical pipe, F,

which passes centrally through the steam` Y boiler and its dome, thus forming a magazine or conduitfor supplying the furnace with fuel from the inside of the car. The body cot' this cap is made hollow and filled with plaster-ofparis or some other non-conductor of heat, whereby the exposed top of the cap will not become hot. This pipe F is secured at its lower end in the bottom of the boiler and passes through the same, and, it' desired, can be extended to within a short distance from the tire-grate, as shown in dotted lines, thereby forming a self-feeder or magazine for fuel. The upper end of this pipe is swelled into the upper end of the dome, which has an inner annular flange, e', just below its upper edge. This iiange tits the pipe F, and by being made 'lower than the upper edge ofthe dome an anthe top ofthe plate D, thus presenting no obstruction along the door. Ample steam-space is left between the walls of the dome and the pipe F, and pipe-connection is made with Athe steam dome for the purpose of conveying steam to the radiators, and at the same time protect wood-work from danger by lire.

The furnace G is composed of three sections, the upper one,g, of which surrounds the lower portion of the boiler. This upper section of the furnace-shell is flanged around its upper edge and secured to the boiler by bolts, which are passed through its flange and through the ange a. of the boiler.4 vThe lower sections, g' g2, of the furnace, which respectively provide the fire-box Hand ash-pit I, are flanged and bolted together at their meeting edges, the section g being also flanged at its top edge and bolted to the upper section, g. The smokepipe L leads from the upper section of the furnace and is conducted to any desired point.

K indicates the grate, which rests in an an- IOO nular seat formed in the lower or third section of the furnace. An arm, 7c, ot this grate extends through an opening in the side of the furnace and connects with a cranl; end ot' the rod M, which enters a slot in the arm of the grate.- This rod extends up through a bearing, m, cast with one of the furnace-sections, and also passes up through the angea of the boiler, whereby upper and lower bearings are provided for the rod. The upper end ot' this rod extends in an opening in plate D, and can be squared so that it can be caught by some suitable shaker and operated by an attendant within the car.

The bottom of the ash-pit has two or more openings for the discharge ot' ashes. These openings are closed by a rotary damper or grate, N, which consists of a plate provided with suitable openings and pivoted to the under side of the furnace, which said plate can also be operated by an attendant within lthe car by providing an attachment or rod-connection similar to that used for the grate. The furnace is formed with an inlet or shaft passage, O, at its base. This passage is closed by a hinged door, P, which drops over the mouth of the passage by its own weight. It is proposed to cause this door to be opened automatically, and to a greater or less extent, according to the requirement ot' the lire. To such end 1 connect the tubular neck of a shell, Q, with the top of the boiler, and within said shell I arrange a exible diaphragm, q, which connects with a lever, R, by means ot' a plunger-rod, i', working through the top ot1 the shell. This plunger-rod connects with the pivl oted lever R, which is pivoted at one end, and

at its remaining end connected with a lever, S, by means of a link, s. This lower lever connects with the ash-pit door P by means of a chain,$2,011equivalentconnection5 hence when there is an excess of heat and steam the'latter will force the diaphragm up, and, through the medium ot" the links, levers, and connections hereinbefore described, slaeken the chains and allow the door to close., so as cut ot't' the draft,

and thereby lower the tire; It is also proposed to work a similar damper in the smoke-pipe in close connection with the one at bottom ot' furnace by the same device and by the same plunger and lever-connection.

As this heater will be located at or about the under side ot' the car, the steam-pipe will radiate out from the heater to the sides ofthe car.

U indicates the steam-pipes leading from the dome under the door to the sides of the i2 l acarrea car. Each pipe rises above the floor at the side of the car, as indicated in Fig. 2, and connects with a radiator or with the branch pipes U', which run to the end of the car and are then returned to the boiler. The steam entering the pipes from the dome passes through the pipes, thereby heating the same. The water ot' condensation is conducted back into the boiler, so that there is a. constant circulation through the pipes.

Having thus described my invention, what I claim is u 1. A boiler for railwayheaters, east with a shortcylindrical body, and with a tubular dome or steam-jacket which rises centrally from the top of the boiler and enters an opening in the loor ofthe car, and having a central tube passing down through the dome and opening into the tire-box, a stcanrspace being left between said tube and the steam-dome throughout thel the wall ofthe ash-pit, said -grate having an.

arm passing through an opening in the fire- Y box and engaging with the crank-pin of a vertiealshat'thaving its bearings in tianges formed on the furnace and extending upward into a recess in thev tloor ofthe saine.

4.. A heater for cars, consisting ot' the boiler having closed tubes extending into the firebox, a steam-dome rising to the floor ot' the car, a tube iuclosed by said dome, with an intervening steanrspace, said tube being provided with a suitable cap, and a gra-te seated in an annular recess in the wall of the ash-pit and connected with a crank-pin upon a vertical shaft, the squared end ot' the latter being arranged in a recess in the car-iloor, substantially as described.

In testimony whereofl have hereunto set my hand in the presence ot' two subscribing witnesses.

WILLARD M. FULLER.
